A rational chemical structure design is inevitable to obtain requested properties of functional organic materials in various applications. In this presentation, conjugated polymer and molecular systems designed to exhibit unique optical property based on controlled interaction between molecules and surrounding environment will be introduced to realize stimuli responsive hybrid materials system for sensor and optical applications. First, utilizing conjugated polymers with tailored unique optical property, latent optical information encoding is demonstrated that reveals and conceals hidden information upon aggregation/deaggregation of conjugated polymers. Also, a highly selective alcohol and water sensor is devised based on the controlled interaction differences between fluorescent molecules and environment including ceramic substrates and analyte solvents. The sensor array can clearly discriminate physicochemically similar liquids such as ethanol, methanol, ethylene glycol, and water. |
